FIELD OF THE INVENTION

[0001] The present invention relates generally to a method and apparatus for loading objects into packages and more particularly, but not exclusively to a method and apparatus that loads various sizes of cuts of meat into plastic bags.

BACKGROUND ART

[0002] There is an urgent need in the meat packing industry to reduce labor costs and improve overall efficiency. One area in which the meat packing industry can achieve these objectives is the area of packing cuts of meat into plastic bags.

[0003] As an animal carcass is processed in a meat packing plant, the carcass travels along various conveyors and is separated into the various cuts of meat at different workstations. Meat packing plants pack various cuts of meat, such as striploins, tenderloins and rumps, into plastic bags prior to shipment. In some meat plants, the various cuts of meat are sorted and each cut is eventually placed on a specific conveyor with like cuts and then delivered to a workroom where it is then packed into a package, such as a plastic bag. In other plants, the various cuts of meat are not sorted and are all placed on the same conveyor, where the various cuts are packed into plastic bags.

[0004] The process of loading the cuts of meat into plastic bags has been done manually by a person who picks the cut of meat up off the line and places it into a plastic bag and then returns the bagged meat onto another line or conveyor so it can travel to the next station. Machines have also been used in an effort to automate the process of loading cuts of meat into plastic bags. Traditional manual methods and machines used by the meat packing industry have proved to have disadvantages and limitations. For example, some machines use a pneumatic ram that forces or stuffs the meat into the bag. These machines can only handle certain widths of cuts of meat and cannot be used to pack cuts that are not rigid and are easily deformable. As a result, additional lines are needed in a meat packing plant to handle the cuts of meat that cannot be fed into this type of machine. The additional lines take up valuable floor space that could be better used for other functions.

[0005] Another known machine for bagging cuts of meat is a belt loader machine. Belt loaders have numerous conveyor belts that transport a cut of meat into a bag as the bag is pulled over the ends of the belts. To accommodate the number of conveyor belts and the thickness of each of the conveyor belts, use of larger, oversized bags is required. Furthermore, a worker must have a high degree of skill to efficiently operate and bag meat on a belt loader machine.

[0006] Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.

OBJECTS OF THE INVENTION

[0007] It is one of the principal objectives of one embodiment of the present invention to provide a machine for loading objects, such as cuts of meat, into bags which overcomes or alleviates problems in machines for loading objects at present.

[0008] It is another objective of one embodiment of the present invention to provide an apparatus that reduces labor involved with packing cuts of meat into plastic bags.

[0009] It is another objective of one embodiment of the present invention to automate the meat packing process.

[0010] It is another objective of one embodiment of the present invention to reduce costs in packing meat by reducing the use of oversized plastic bags.

[0011] It is another objective of one embodiment of the present invention to improve the overall efficiency of the meat packing process.

DETAILED DESCRIPTION OF THE DRAWINGS

[0031] While the present loading device is susceptible of several constructions, there is shown in FIG. 1, a system and apparatus for loading cuts of meat into bags according to the present invention. The system shown is adapted for use in a meat packing plant and designed to be placed in a production line that carries meat from a main conveyor 10, to a vacuum pack station 12. However, those skilled in the relevant arts will appreciate that the present invention will also have applications other than meat packing.

[0032] The upstream or infeed conveyor assembly of the system includes a timing conveyor 18 and a scale conveyor 17. These may be automatically operated to ensure that only a single cut of meat is present on the timing conveyor at any one time, allowing the timing conveyor 18 to transport individual cuts of meat to a loading fork carriage assembly 22, which bags the cuts of meat. One or more further conveyors, in this case three conveyors 10, 14 and 16 may be provided to accumulate and control the movement of cuts of meat to the scale conveyor 17 and/or timing conveyor 18. Those skilled in the relevant arts will appreciate that there a numerous control strategies that may be used for conveying cuts of meat to the timing conveyor 18. The downstream or take-away conveyor assembly of the system includes a take-away conveyor 20 which transports the bagged meat 142 to the vacuum pack station 12. In between the upstream conveyor assembly and the downstream conveyor assembly is the loading fork carriage assembly 22.

[0033] The main conveyor 10 transports a product, such as a cut of meat 142, from the cutting area (not shown) to an optional accumulating station 14. At the accumulating station 14, the cuts of meat are accumulated and held until they are placed onto the infeed conveyor 16. The infeed conveyor 16, scale conveyor 17 are operated to separate or space the individual cuts of meat before they reach the timing conveyor 18. The timing conveyor 18 can have guides (not shown) thereon. The guides center the cuts of meat so that they are positioned exactly in the middle of the timing conveyor 18 as they are fed to the loading fork carriage assembly 22.

[0034] The timing conveyor 18 moves at a controlled speed. By controlling the speed of the timing conveyor 18 along with the alignment and separation of the cuts of meat, a desired spacing and timing between the cuts of meat reaching the end of the timing conveyor 18 is achieved so as to coincide with the travel of a loading fork 60 below the end of the timing conveyor 18 (see herein below).

[0035] A sensor can be provided on or near the scale conveyor 17 or timing conveyor 18 to detect each cut of meat as it passes a certain point. When a cut of meat is detected, the sensor sends a signal to a controller indicating that a cut of meat will be delivered to the loading fork carriage assembly 22 at a known time.

[0036] The scale conveyor 17 can contain an in-line belt scale that can weigh each cut of meat to be bagged. An automatic cut-sizing device 24 can also be installed on or near the scale conveyor 17 or the infeed conveyor 16 to detect information about the size of the cut of meat. The sensor, the cut-sizing device 24 and belt scale can all be coupled to a controller in order to send information to the controller that can be used for a variety of purposes, some of which are described below. A variety of exemplary uses are also described in PCT/NZ97/00127, which is hereby incorporated by reference.

[0037] Also shown in FIG. 1 is a wall 30 of six of machines 31, 32, 33, 34, 35 and 36 that produce plastic bags. These machines 31, 32, 33, 34, 35 and 36 are shown schematically, but can be of the type described in U.S. Pat. No. 5,618,252 and 5,816,990, which are hereby incorporated by reference. The machines 31, 32, 33, 34, 35 and 36 can contain various widths of plastic material so that a variety of width bags can be produced depending on the size of the cut of meat to be bagged. The width of the bag to be produced can be determined from the information the controller receives from the in-line belt-scale and cut-sizing device 24. The controller can be coupled to the machines 31, 32, 33, 34, 35 and 36 and can send a signal to instruct a specific machine to make a bag for a particular cut of meat. The information can also be used to print certain information about the cut of meat directly onto the bag or on tags, labels or other identifying devices that can be used in association with the bags or meat.

[0038] As shown in FIGS. 2-6, the loading fork carriage assembly 22 has an upstream frame support member 40 and a downstream frame support member 42. The upstream frame support member 40 is positioned near and partly underneath, the timing conveyor 18. The downstream frame support member 42 is positioned near the take-away conveyor 20. The two frame support members 40 and 42 support a loading fork frame 44. The loading fork frame 44 is rotationally mounted to the frame support members 40 and 42 by pins 46 and 48. A motor 51 on the upstream support member 40 controls the rotational movement of the frame 44 and causes the frame 44 to rotate about the pins 46 and 48. The frame 44 has two sets of rails 50 and 52, the first set of rails 50 is shown on the upper side of the frame 44 in FIGS. 2-5 and the second set of rails 52 is shown on the lower side of the frame 44 in FIGS. 2-5. In FIG. 6, the set of rails 50 is on the lower side and the set of rails 52 is on the upper side.

[0039] One of the forks 60 is mounted on a first set of rails 50. The other fork 62 is mounted on a second set of rails 52. The rails 50 and 52 can be I-beams, rods, box sections or any other commonly used member that allows loading forks 60 and 62 to move longitudinally with respect to the frame 44. The loading forks 60 and 62 are movable along the rails 50 and 52 by a drive belt. Any other suitable means to move the loading forks may be used as required. The belt is driven by a motor and drives both the forks 60 and 62 along the rails 50 and 52, respectively. The upper fork 60 moves from the position shown in FIG. 2 along its rails 50 in the downstream direction, i.e., from the timing conveyor 18 towards the take away conveyor 20, while the lower fork 62 moves along its rails 52 in reciprocal opposite movement in an upstream direction. The upper fork 60 advances along the rails 50 at the same speed and direction as the timing conveyor 18, so that, as the cut falls off the end of the timing conveyor 18 the end of the loading fork 60 meets the leading edge of the cut of meat.

[0040] Referring now to FIG. 7, one of the forks 60 is shown. The loading fork 60 has a center shoe 70 which has a left portion 72 and right portion 73 which slope upwardly and outwardly from a lower central point. The center shoe 70 is preferably approximately 100 mm wide and 800 mm long. The center shoe 70 may be slightly cupped or V-shaped to hold the cut of meat. Due to its shape the center shoe 70 is able to hold smaller cuts of meat as well as larger cuts of meat.

[0041] The fork 60 also has two inner fingers 74 and 76. Preferably, the inner fingers 74 and 76 are stainless steel tubes which are approximately 10 mm in diameter. The inner fingers 74 and 76 are preferably approximately 700 mm long. The back ends 78 and 80 of the inner fingers 74 and 76 extend approximately 20 mm behind a loading fork cross piece 82 and the front ends 83 and 84 of the fingers 74 and 76 extend approximately 700 mm forward of the cross piece 82.

[0042] The fork 60 also has two outer fingers 86 and 88. Preferably, the outer fingers 86 and 88 are also stainless steel tubes which are approximately 10 mm in diameter and approximately 600 mm long. The inner fingers 74 and 76 and outer fingers 86 and 88 are preferably generally tubular and hollow, but can be any shape that will adequately support the cuts of meat. The inner fingers 74, 76 are positioned slightly higher than the center shoe 70, and the outer fingers 86 and 88 are positioned slightly higher than the inner fingers 74 and 76. The overall configuration of the fork 60 is generally V-shaped to hold the cuts of meat better and to be able to hold a variety of sizes of meat.

[0043] The hollow inner fingers 74 and 76 allow air to be blown therethrough. A compressor (not shown) can be coupled to the fingers 74 and 76 by tubes 77 and 79 and blow compressed air into the back ends 78 and 80 of the fingers 74 and 76 through the tubes 77 and 79. Near the back ends 78 and 80 of the fingers 74 and 76, there are two venting holes 90 and 92, which are approximately 3 mm in diameter. The holes 90 and 92 are drilled through the fingers 74 and 76 to allow more air to enter the fingers 74 and 76 when the compressed air is being blown into the fingers 74 and 76 by the compressor. The air is blown through the inner fingers 74 and 76 and out holes 94 and 96 in the front ends 83 and 84 of the fingers 74 and 76. A deflector 100 is positioned at the front end 83 and 84 of each of the fingers 74 and 76 to direct the air slightly upwardly to facilitate opening the bag by lifting the bag away from the cut of meat, making it easier to pull the bag over the cut of meat and fork 60. The deflectors 100 may be integrally formed from fingers 74 and 76 by cutting a slot at the top surface near the end of each finger 74 and 76. In one embodiment of the present invention, inner fingers 74 and 76 are stainless steel hollow tubes with capped front ends 83 and 84. In this embodiment, the deflectors 100 are formed by cutting and removing a portion of the top surface of the capped inner fingers 74 and 76 at a 45 degree angle leaving the capped ends in place as deflectors 100. In such an embodiment, air flows through the inner fingers 74 and 76, makes contact with the sloped capped ends of fingers 74 and 76, and is directed upwards at a 45 degree angle through the opening created by the removal of the portion of the top surface of the inner fingers 74 and 76.

[0044] The air blown out holes 94 and 96 may be particularly useful if a loading horn is not used. An operator may place the bag directly onto the fork 60 about the cut of meat. The air may assist the operator to open the bag, which can be time consuming as it is often difficult to separate the sides of the bag.

[0045] The fork 60 is supported by a frame 98 which is attached to the cross piece 82 of the fork 60, so that the fork 60, when mounted on the frame 98 looks like a sideways U with the open end forward and half the leading edge of the lower arm removed. The objective is to centrally support the fork 60, while allowing the bag to be pulled the full length of the fork 60 without restriction.

[0046] Referring now to FIGS. 8 and 9, the loading horn 110 can have two side plates 112 and 114, which are generally triangular in shape with the apexes 116 and 118 to the front edge of the side plates 112 and 114 so that a bag can be easily pulled onto the front edge of the loading horn 116 and 118. In the closed position shown in FIG. 8, the rear edges of the side plates 112 and 114 form an opening that is preferably approximately 100 mm wide. The front edges of the side plates 112 and 114 are virtually closed to allow the bag to be easily pulled over.

[0047] Once the bag is pulled onto the loading horn 110 a sensor (not shown) can detect the placement of the bag and the horn 110 is moved to an open position shown in FIG. 9. The front edges of the side plates 112 and 114 are pulled apart by pneumatic rams 120 and 122 (see also FIGS. 3 and 4) until further expansion of the plates 112 and 114 is restricted by the bag, thus holding the bag in place on the loading horn 110. The rams can also stretch the bag outwardly to allow a larger cut of meat to be placed in the bag.

[0048] The front edges of the loading horn 110 may be flared slightly outwardly so the fingers 74, 76, 86, 88 of the loading fork 60 can hit the horn 110 and push the horn 110 outwards allowing the fork 60 or a central portion of it to pass inside the horn 110 and avoiding the loading fork 60 hitting the edge of the loading horn 110.

[0049] In one embodiment of the invention, the loading fork 60 retracts from the loading horn 110 once a bag has been pulled over the cut of meat. Once the cut has passed through the loading horn 110 and the bag has been pulled off it by the action of the loading fork 60 passing through the horn 110, the pneumatic rams 120 and 122 return the loading horn 110 from its open position (FIG. 9) back to the closed position (FIG. 8), thus preventing the cut from returning with the fork 60 as the loading fork 60 retracts and allowing the loading horn 110 to be ready to accept the next bag. This retraction of the loading fork 60 is required for smaller bags, where the loading horn 110 extends only around an inner portion of the loading fork 60. For larger bags where the outer fingers 86, 88 pass through the center of the loading horn 110, the loading fork may optionally continue through the loading horn 110 along with the bagged cut of meat.

[0050] The loading horn 110 is mounted to a frame 130 that suspends the horn 110 over the loading fork frame 44 (see FIGS. 2-6.). The horn 110 can be fixedly mounted on to the frame 44, or can be mounted on rails 132 and 134 so that the horn 110 can move relative to the loading fork frame 44.

[0051] In another embodiment of the invention, which may be preferred due to avoiding the requirement for the abovementioned retraction of the loading fork 60, the loading horn 110 may be modified to allow the loading fork 60 to continue through the loading horn 110 along with the bagged cut of meat even when the bag only extends over an inner portion of the loading fork 60, for example, extending over the inner fingers 74, 76 and not the outer fingers 86, 88. The modified loading horn includes an upper and lower portion and opens along a substantially vertical axis, rather than along the horizontal axis of the loading horn 110. The lower portion includes a split to allow the loading fork 60 to travel past it. More particularly, the lower portion includes a split that provides a channel along which the frame 98 (see FIG. 7) can travel.

[0052] The modified loading horn may include a number of horizontally spaced fingers along its upper lower portions, allowing an operator to place a bag around the appropriate fingers according to its size. The upper portion may be pivotally engaged to a frame to allow the distal end, corresponding to apexes 116, 118 of the loading horn 110, to pivot down towards the lower portion to place the modified loading horn in a closed position to enable easier placement of bags onto the horn. The upper portion would pivot upwards into an open position to hold the bag ready for placement of a cut of meat therein. Alternatively, the upper and lower portions may remain substantially parallel to each other and move vertically relative to each other to open and close the loading horn.

[0053] In a further alternative embodiment, a further modified loading horn may be used to avoid an operator having to select the fingers of the loading horn. The further modified loading horn has upper and lower portions and opens vertically like the modified loading horn described above. The lower portion of the further modified loading horn includes two horizontally moveable parts that are together in when in a closed position and apart in the horizontal plane when in an open position. The movement of the two parts between the closed and open position would correspond to the movement of the upper and lower portions between the closed and open position. The upper portion of the further modified loading horn may also include two parts that reflect the movements of the lower portion parts, resulting in the opening of the bag being held in a square shape to receive cuts of meat. If the upper portion has only a single part, larger bags may be held in a triangular or trapezoidal shape to receive cuts of meat. If more than four moveable parts are provided, the bag may be held open in different shapes, although it is not anticipated that this will be required for meat cuts.

[0054] Should the loading fork 60 be mounted on a different frame 98, not having a central support member, the split in the lower portion of the horn in the modified and further modified loading horns may need to be moved correspondingly.

[0055] What loading horn is used (loading horn 110, the modified loading horn, or the further modified loading horn) will depend on the requirements for the particular application. For example, cost considerations and the relative complexity and number of actuating mechanisms required to move the parts or portions of the loading horn may affect which horn is most suitable.

[0056] Referring now to FIGS. 3-6, operation of the loading device will be described. The loading fork 60, receives the cut of meat from the timing conveyor 18. Because the meat is positioned in the center of the timing conveyor 18, it falls onto the center of the loading fork 60 (FIG. 4). The loading horn 110 has a bag 140 over it and is moved to its open position prior to the fork 60 reaching it. Then the fork 60, carrying the cut of meat on the center shoe 70 and fingers 74, 76, 86 and 88 (depending on the size of the cut of meat) travels along the rails 50 and through the open loading horn 110 over which a bag (not shown) of the correct size has been pulled. The loading fork 60 can continue with the product now inside the bag, and emerge on the other side of the horn 110, removing the bag from the horn 110 (FIG. 5).

[0057] As shown in FIG. 6, once the upper loading fork 60 with the cut of meat encased within the bag reaches the end of the first set of rails 50, the frame 44 rotates 180 degrees so that the upper loading fork 60 with the bagged product is positioned upside down and becomes the lower loading fork and the other, empty fork 62 is brought into an upright position, just underneath the timing conveyor 18 becoming ready to receive the next cut of meat.

[0058] The bagged product 141 is suspended from the loading fork 60. The take-away conveyor 20 can be positioned underneath the upside down fork 60 containing the bagged, suspended product. The take-away conveyor 20 could rise, taking the weight of the product off the loading fork 60 and thereby pulling the bagged product from the fork 60 and transporting the product to its destination, leaving the loading fork 60 behind. Other options for removing a bagged cut of meat from the fork 60 can include, but are not limited to, any of the following alternatives.

[0059] The take-away conveyor 20 can be controlled by weight sensors (not shown) such that when the sensors detect a bagged cut of meat, the take-away conveyor 20 lifts the cut from the loading fork 60 and transport the cut away. The loading fork 60 can be hinged such that the loading fork 60 may pivot in its inverted horizontal position and drop a suspended bagged cut of meat a short distance onto the take-away conveyor 20. Similarly, the tipping loading fork 60 may come to rest on the take-away conveyor 20 allowing the take-away conveyor 20 to assume the load and remove the bagged cut of meat from the loading fork 60. Furthermore, an unloading arm (not shown) can sweep a suspended bagged cut of meat from the loading fork 60 onto the take-away conveyor 20.

[0060] Alternatively, when the loading fork 60 carrying a bagged cut of meat reaches the end of the upper rails 50, the loading fork 60 may come to a stop and a bagged cut of meat can be manually removed from the loading fork 60 and placed on the take-away conveyor 20 before the frame 44 rotates 180 degrees. Similarly, a bagged cut of meat may be swept off the loading fork 60 onto the take-away conveyor 20 by an unloading arm prior to the frame 44 rotation.

[0061] The loading forks 60 and drive belt may be configured such that when the loading fork 60 travelling along the upper rails 50 reaches the end of the upper rails 50 the drive belt passes over a horizontal pulley (not shown) thereby tipping the loading fork 60 from a horizontal position along the upper rails 50 through a vertical position and into an inverted horizontal position along the lower rails 52. In this configuration, the bagged cut of meat can fall from under its own weight from the tipping loading fork 60 to the take-away conveyor 20.

[0062] The loading horn 110 can be further enhanced by a vacuum head or heads (not shown), which secure the bag to the loading horn 110 as the operator places the bag in position.

[0063] Further, the bag can be conveyed to the loading horn 110 by a vacuum head (not shown). The vacuum head selects the bag produced by a bagger machine such as the machine disclosed in U.S. Pat. No. 5,816,990 and delivers the bag to the loading horn 110. This vacuum head bag transportation device can be one such as the one disclosed in U.S. Pat. No. 5,618,252.

[0064] From the foregoing description, it will be apparent that the loading machine of the present invention has a number of advantages, some of which have been described above and others of which are inherent in the machine 10 of the present invention. Also, it will be understood that modifications can be made to the loading machine of the present invention without departing from the teachings of the invention.
